LITS.jl -- An Open-Source Julia based Simulation Toolbox for Low-Inertia Power Systems
摘要：
可再生能源的变流器接口发电（CIG）的集成对电力电力系统的稳定性和暂态行为提出了挑战。了解低惯性电力系统的动态行为对于解决这些稳定性问题至关重要。然而，明确面向低惯性系统建模的开源工具有限。在本文中，我们开发了一个开源的仿真工具箱，以研究高渗透情况下的瞬态响应。jl是用Julia计算语言实现的，具有多机建模能力，丰富的同步发电机组件库（AVR、PSS、调速器等）和逆变器配置。进行了几个案例研究，并根据现有的工具箱进行了基准测试和验证。案例研究被选择来展示不同设备模型的行为在电力系统中的集成。
英文摘要：
The integration of converter-interfaced generation (CIG) from renewable energy sources poses challenges to the stability and transient behavior of electric power systems. Understanding the dynamic behavior of low-inertia power systems is critical to addressing these stability questions. However, there is a limited availability of open source tools explicitly geared towards low-inertia systems modeling. In this paper, we develop an open source simulation toolbox to study transient responses under high penetration scenarios. LITS.jl is implemented in the Julia computing language and features multi-machine modeling capability, a rich library of synchronous generators components (AVR, PSS, Governor, etc.) and inverter configurations. Several case studies are conducted and benchmarked and validated against existing toolboxes. Case studies are selected to showcase the integration of different device models' behavior in power systems.
